Maria Caulfield: I will not stand at the Dispatch Box and deny any of the instances that we have seen, their consequences or the failings that have been identified. I apologised in my opening remarks for the care that failed the most vulnerable patients in our system. I commit to right hon. and hon. Members from the Dispatch Box that we are urgently looking not just at these cases but across all mental health in-patient services, and not just at adult mental health, but at offenders and other users of mental health facilities.
We have brought in a number of measures. We introduced new legislation, which was enacted in March, on the use of force and restraint. We are identifying best practice and trying to get that rolled out across the country. We are looking at putting in place a number of measures to improve safety and to support staff in units where staff shortages have been identified as a cause of the problems.
With regard to the hon. Lady writing to the Secretary of State, I signed off a letter to her early on Tuesday, which she should receive any day now. I apologise that she did not previously get responses in a timely manner.
NHS England has commissioned a system-wide investigation into the safety and quality of services across the board, particularly around children and adolescent mental health services. I am pushing for those investigations to be as swift as possible.
On the issue of a public inquiry, I am not necessarily saying that there will not be one, but it needs to be national, not on an individual trust basis. As we have seen in maternity services, when we repeat these inquiries, they often produce the same information and we need to learn systemically how to reduce such failings. My issue  with public inquiries is that they are not timely and can take many years, and we clearly have cases that need to be urgently reviewed and to have some urgent action taken on them now. I will look at the hon. Lady’s request but, as I said, the Secretary of State and I are taking urgent advice, because we take this issue extremely seriously. One death from a failing of care is one death too many.
